Crotogino, Jennifer. "Visual stress in migraine : subjective and psychophysiological responses to intense visual stimulation". Thesis, McGill University, 2002. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=38475.
Texto completo da fonteThe first study assessed thresholds of light-induced discomfort and pain in migraine sufferers and non-migrainous controls during a non-headache period. Two instruction sets were compared to assess whether information presented to participants would affect thresholds. The results showed that migraineurs had significantly lower thresholds for light-induced pain. However, this effect was most apparent in those who had heard the negatively biased instructions reinforcing the need to control contextual factors when assessing subjective phenomena such as visual discomfort.
The second study assessed subjective and psychophysiological responses of female migraine sufferers and female controls during exposure to visual stimuli incorporating spatial and temporal characteristics that are most likely to be bothersome to migraineurs. Two control stimuli were included to assess responses during similar, but theoretically less aversive conditions. Migraine sufferers had higher heart rate and more frequent electrodermal responses than controls at all points of the study, including baseline and recovery. However, while migraineurs reported higher anxiety during the intense conditions, and reported more visual and somatic complaints than controls during various viewing conditions, they did not show heart rate, heart rate variability or electrodermal changes that would suggest clear changes in autonomic function in response to aversive visual stimulation.
The third study assessed ambulatory electrocardiograms to investigate whether autonomic changes would be evident in the period leading up to, during or following a migraine. Three individuals were assessed on a day when they experienced a naturally occurring headache, and on a day when they were not. No obvious pattern of autonomic change was detected before or after headache, although there was some evidence that a pattern of increased heart rate and decreased vagal tone may accompany headache.
In summary, the results confirm that migraine sufferers are more sensitive to intense visual stimulation than controls, but do not support the contention that exposure results in widespread autonomic changes. Since interictal visual discomfort is a common in migraine, further research is needed to clarify how it can be incorporated into models of migraine pathophysiology.

Texto completo da fonteIn this thesis, the Laser-assisted Atom Probe Tomography is coupled in-situ with a photoluminescence (PL) bench, where the pulsed laser radiation is used to trigger the ion evaporation from the specimens and, simultaneously, to activate the emission from optically active centers present into the material. For this work, two different materials were selected: diamond nano-needles with embed- ded optically active defects (color centers) and a ZnO/(Mg,Zn)O multi-quantum-well (MQW) heterostructure, which contains quantum emitters of different thicknesses. Thanks to this original photoluminescence setup, the influence of the electric field on the fine structure of some color centers, embedded into the diamond nanoneedles, was observed. The first study focused on the neutral nitrogen-vacancy center (NV0), which is one among the most studied color centers in literature. The evolution of the NV0 optical signature, as a function of the applied bias, allowed to evaluate the mechanical stress (> 1 GPa) and the electric-field acting on diamond tips. These results demon- strate an original new method to perform contactless piezo-spectroscopy of nanoscale systems under uniaxial tensile stress, generated by the electric field. This method was applied also on another color center, which nature is still not clear in literature, emitting at 2.65 eV, and more sensitive than the NV0 color centers to the stress/strain field. New results on its opto-mechanical properties were obtained, but its identity still needs to be understood. Since the evaporation field of diamond is really high, the diamond nanoneedles were not analyzed using La-APT. Therefore the coupled in-situ technique was applied in order to study the ZnO/(Mg,Zn)O MQW heterostructure, accessing to the structure, composition and optical signature of the probed specimen in only one experiment. The photoluminescence spectra acquired by the specimen during its ongoing evaporation represents a unique source of information for the understanding of the mechanism of light-matter interaction and the physics of photoemission under high electric field. The correlation of the structural and optical information, related to this MQW heterostructure, demonstrates that the coupled in-situ technique can overlap the diffraction limit of the PL laser and that, as done for the diamond nanoneedles, is pos- sible to estimate the induced-tensile-stress. The results achieved by the in-situ coupling of the La-APT technique with the PL spec- troscopy show that such instrument is an innovative and powerful technique to perform research at the nanometric scale. For this reason, this work can open new perspectives for a deeply understanding of the physicics related to the studied systems in parallel with the continuous enhancement of the experimental setup

Texto completo da fonteO esporte de alto nível exige uma rotina de treinamento intenso, jogadores de futsal de alto nível são expostos a diversas situações que podem provocar declínio na sua performance ao longo de uma temporada. Portanto, o objetivo desse estudo foi verificar marcadores funcionais e bioquímicos ao longo de uma temporada de competição. Foram estudados oito jogadores de futsal submetidos a três testes de esforço máximo durante o ano competitivo: Pré temporada (T1), Período Competitivo (T2) e Final de Período Competitivo (T3). Foram mensurados parâmetros funcionais e, também, amostras de sangue para contagem de células, perfil lipídico, marcadores de inflamação, dano muscular e estresse oxidativo realizados antes e depois um teste máximo de VO₂ em cada período. Não foram encontradas diferenças significativas nos parâmetros funcionais, nem no perfil lipídico. No entanto, foram encontradas diferenças relativas ao número de neutrófilos, monócitos, hemoglobina, creatina quinase, proteína c-reativa, albumina modificada por isquemia e produto proteico de oxidação avançada nos diferentes períodos da temporada. Lactato sanguíneo e lactato desidrogenase mostraram diferenças dentro dos testes pré x pós. Os menores níveis de inflamação, estresse oxidativo e marcadores de dano muscular foram encontrados no T2 em relação ao T1 e T3, indicando que os jogadores se adaptaram as cargas de treinamento. Embora sejam necessários estudos complementares, parece que uma rotina de análises de marcadores bioquímicos pode ser utilizada para um controle dessa população.

Texto completo da fonteThe on-going climate changes that we are facing are characterized in particular by modifications of temperature profiles in terms of intensity, duration and repetition of heat waves. These heat waves occur during the reproductive stages of the crops, which are also the most critical for seed yield elaboration and grain quality in crops. Oleaginous species such as rapeseed and camelina, are species particularly impacted by heat stress that cause yield penalties and a lower seed quality. Therefore, to cope with heat stress, it has become necessary to identify new acclimation levers that differ avec genetic and agronomic levers, such as strategies based on plants acclimation. Thermopriming which consist in priming the plants in a way to help them respond more rapidly, effectively, intensively and/or sensitively to heat by a prior exposure of a stress of the same nature could allow the plants to acclimate and develop appropriate response mechanisms. The plant inoculation with Plant Growth Promoting Rhizobacteria (PGPR)-type bacteria is also an acclimation lever increasingly studied, that limit the impacts of abiotic stress such as heat stress. However, although these two types of acclimation levers are mainly studied to limit stress impact on aboveground development and yield, few studies have observed their effects on root morphology and functions such as root exudation. In this thesis we analysed in rapeseed and camelina (i) the effects of a gradual increase in temperature prior a heat stress on yield and grain quality and on root morphology and exudation and (ii) the effects of inoculating two Pseudomonas with PGPR activities in order to limit the impact of heat stress on yield and grain quality. Moreover, in order to understand the impact of heat stress and PGPR inoculation (combined or not) on the plant and associated rhizosphere, the effects of these treatments were studied on root exudation, carbon (C) allocation in the soil-plant system, root morphological traits and soil microbial communities. Our results showed that rapeseed and camelina have contrasting strategies in terms of response to heat stress. Indeed, camelina seems to respond to the stress by increasing its investment to the roots thus improving the quality of exudation and stimulating the activity of microbial communities, unlike rapeseed, which seems to undergo heat stress. In addition, these two species respond differently to the two acclimation strategies applied. In rapeseed, thermopriming reduced C exudation and maintained yield and grain quality, whereas it had a more negative impact on exudation and root morphology in camelina. PGPR inoculation is an acclimation strategy that tends to limit the effects of heat stress on yield and grain quality in rapeseed. However, PGPRs act as an additional sink in rapeseed, impacting its development, exudation and the activity and composition of microbial communities in the rhizosphere. By contrast, camelina is slightly affected by the addition of PGPRs and seems to control the plant/bacteria interactions rather than be affected by them. In short, beneficial effects on plants of these acclimation levers have been evidenced. In addition, it could be interesting to integrate the effects of varietal selection on plant response strategies to stress, and in particular the variability of root functions and interactions with the rhizosphere, in the light of the varietal selection differentially undergone by rapeseed and camelina

Texto completo da fontePost-Traumatic Stress Disorder (PTSD) is a mental disorder that affects some individuals exposed to high-intensity stress. The heterogeneity in the expression of various symptoms could explain the lack of effective treatment and/or patient relapse. These subtypes of symptoms are associated with specific brain activities; their better understanding appears crucial for the pursuit of more personalized and thus more effective treatment. In this context, the behavior of outbred mice was evaluated through various tests for 28 days after receiving two high- intensity electric shocks. An analysis of behavioral profiles in two steps revealed three phenotypes in animals exposed to high-intensity stress. The first step, based on a composite score of generalized anxiety-like behaviors, allowed for the differentiation of resilient and susceptible animals and the establishment of a severity score for behavioral alterations. The second step, focused on persistent defensive behaviors during different re-exposures to stimuli associated with electric shocks, identified two behavioral phenotypes in susceptible animals: immobile and fleeing. Analysis of the cellular expression of the Fos protein highlighted distinct cellular activations in the amygdala (AMG) and the periaqueductal gray matter (PAG). Specifically, the severity of PTSD- like behavioral alterations is positively correlated with right AMG activation, and susceptible phenotypes are associated with different activations along the anteroposterior axis of the PAG. Sleep analysis also revealed differences among the three animal phenotypes. In particular, rapid eye movement (REM) sleep appears to be a marker of post-exposure resilience but also an indicator of susceptibility to pathology development before exposure. In conclusion, by demonstrating distinct brain activations and differential effects on sleep in the three animal phenotypes, this study highlights the importance of analyzing behavioral profiles in mice. Refinement of analysis methods of this kind should enhance the translational validity of the PTSD model, thus opening new perspectives for more personalized treatments

Texto completo da fonteYield stress fluids have amazing mechanical properties: below a particular shear stress, called yield stress, the fluid behaves like a solid. Once the yield stress is exceeded, they flow like a viscous fluid or a gel. This thesis deals with the effects of magnetic volume forces on these fluids. We study the opportunity of the solid-gel transition from magnetic volume forces created by various magnetic devices. These fluids have no special magnetic properties. It is therefore necessary to create intense magnetic fields to act without contact on these fluids. We study different magnetic configurations that are able to exceed the yield stress in the fluid. The influences of different parameters of the magnetic configurations is explored, including using parametric studies. Our work combine equations of magnetostatic and non-newtonian fluid mechanics. Magnetostatic calculations are carried out analytically, while the mechanical and magneto-mechanical coupling are processed by a finite element analysis software. Magnetic and mechanical conditions required to the solid-gel transition and to the modification of yield stress fluids flows are discussed, using numerical simulations and dimensionless numbers

This method allowed us to realise a complete and detailed analysis of the age-related hearing loss and hypoxia-induced hearing loss structural alterations and their molecular mechanisms. We thus determined the important role of oxidant stress in cochlea degeneration. Aside to the classical damages caused by ROS on DNA, RNA and lipids, the ROS induced apoptosis in selective cochlea regions such as the spiral ganglion and spiral ligament as well as cytoskeleton perturbations in neural cellules of spiral ganglion, all leading to hearing loss. In addition, adaptation mechanisms such as neoangiogenesis settled down in order to decrease against oxidant stress and slow down hearing loss

Texto completo da fonteBackground: Intensive care nurses perceive the Intensive Care Unit (ICU) as a stressful workplace. Patients are critically ill and emergency situations can occur quickly. The environment is high-tech and occasionally a high tempo. Previous stress research has shown that increased levels of stress have a negative impact on health. Stress management is based on problem-focused - or emotion-focused coping strategies. The Aim: To describe the factors that stress critical care nurses, and how they experience and cope with this stress. Method: A qualitative approach with focus group interviews. Five critical care nurses participated. The interview was unstructured with two open questions. The material was analyzed using qualitative content analysis. Results: Three main categories and ten subcategories emerged. The main categories consisted of: Perceived stressors, feelings and experiences of stress and ability to handle stress. During the interview revealed that stress was induced in certain work situations and in particular working environment. This caused feelings of frustration and powerlessness in ICU nurses. Critical care nurses used a variety of coping strategies such as seeking support and plan and organize their work, to cope with stressful situations. Conclusion: It originated results showed that intensive care nurses experienced the feeling of not enough or able to influence their work situation. This in turn led to frustration and stress among critical care nurses. Although this was a high level of comfort. To cope with the present stress chose critical care nurses to seek support from each other as the primary coping strategy Clinical significance: Arrived knowledge from this study may be important for professional’s intensive care nurses and their work environment. Although managers could use this knowledge to organize and provide critical care nurses support.

Nurses are subjected to occupational stress factors that can result in the syndrome of burnout. This study compared levels of burnout in nurses in a medical-surgical ICU setting to those in non-ICU medical-surgical settings. A randomized sample of 40 nurses of an urban hospital in Taiwan, twenty nurses in an ICU and 20 in five non-ICU settings (general medical-surgical wards), who returned the questionnaire used to measure burnout, were included in the study. The instrument utilized was the Staff Burnout Scale for Health Professionals. The study found no significant difference in levels of burnout in the two groups. Both groups in this study experienced a higher level of burnout than was reported in other studies in United States literature. In particular, two general medical-surgical wards which had high patient/nurse ratios, had very high levels of burnout. The study also found that all nurses with lower educational levels and ICU nurses with more years of work experience had more burnout.

Texto completo da fonteSyftet med denna studie var att beskriva i vilka situationer IVA-sjuksköterskor upplever stress och hur de hanterar stressen i det vardagliga arbetet. Studien hade en beskrivande design med kvalitativ ansats. I studien deltog 10 intensivvårdssjuksköterskor. Inklusionskriterierna var att sjuksköterskorna skulle ha en specialistutbildning, och de skulle ha arbetat mer än ett år som intensivvårdsjuksköterska. Data samlades in med en semistrukturerad intervju som varade mellan 7 till 25 minuter. De teman som växte fram under bearbetning av data var ´Låg påverkansmöjlighet, höga arbetskrav och avsaknad av bekräftelse leder till rädsla för att tappa kontrollen´, Obalans mellan krav och bemanning´ samt ´Stödjande faktorer och eget ansvar kan minska stressupplevelsen´. Slutresultatet visade på att IVA-sjuksköterskor upplevde stress i situationer när arbetskraven var för många och ledde till oro för att tappa kontrollen. De höga kraven och otillräcklig bemanning ledde till en obalans där IVA-sjuksköterskorna upplevde otillräcklighet i sitt arbete. Stöd från arbetskollegorna samt individuella sätt att hantera den egna stressen, ansågs vara ett sätt att hantera stress på arbetsplatsen bland intensivvårdssjuksköterskorna. Sammanfattningsvis kan sägas att IVA-sjuksköterskorna upplevde stress på sin arbetsplats av olika orsaker samt att hanteringen av stressen skedde främst via ventilering med arbetskollegor.
The aim of the study was to describe in what situations Intensive Care Unit (ICU) nurses experiences stress and how they cope with the stress in the ordinary work. The study had a descriptive design with a qualitative approach. Ten intensive care nurses took part in the study. The inclusions criteria were that the nurses had an education in intensive care and had worked more than a year as an intensive care nurse. The data were collected with a semi- structured interview that lasted between 7 to 25 minutes. The themes developed from the data were ‘Low influence possibility, high work demands and lack of confirmation leads to fear of loosing the control’, ‘Imbalance between demands and number of staff’, and ‘Supportive factors and own responsibility can reduce the stress experience’ The final result showed that nurses experience stress in situations when the work demands were to high which led to anxiety of loosing control. High demands and insufficient number of staff led to an imbalance and the nurses felt inadequacy in their work. Support from the colleagues and own individual ways to handle the stress, were considered to be ways to cope with it among the nurses. To sum up, the intensive care nurses experienced stress their workplace from various causes and they coped with their stress principally through ventilation with their colleagues.

Texto completo da fonteNa sua profissão, psicólogos dedicam-se a ajudar os seus clientes, de forma a que estes consigam utilizar os seus próprios recursos para lidar com as adversidades das suas experiências. No entanto, para cuidar do outro, tanto profissionais como alunos precisam de cuidar de si mesmos, de forma a minimizar as consequências negativas da prática de psicologia na sua competência e na sua vida privada. Práticas de auto-cuidado estão associadas a um aumento de bem-estar físico e emocional e a uma menor percepção de stress. O presente estudo verificou de que forma práticas de auto-cuidado como a higiene do sono, actividade física, mindfulness e suporte social estão associadas à percepção do stress, quer em estudantes finalistas do mestrado de psicologia como em psicólogos a iniciar a sua carreira. Para tal, aplicou-se a 113 estagiários (43 curriculares e 70 profissionais), o Internacional Physical Activity Questionnaire (2003), o Escala de Stresse Percepcionado (PSS-10) (2010), a Escala Multidimensional de Suporte Social Percebido (2011), a Philadelphia Mindfulness Scale (2008) e o Sleep Hygiene Index (2006), tendo-se traduzido estes dois últimos instrumentos para se prodecer à sua utilização. Verificou-se uma associação estatisticamente significativa nos resultados da higiene do sono (β=0,28, p<0,05) e do suporte social (β=-0,33, p<0,05) nos estagiários profissionais. A continuação desta linha de investigação é necessária para esclarecer que práticas de autocuidado estão associadas à menores índices de percepção de stress, para que se possam implementar programas de práticas de auto-cuidado com estudantes e profissionais de psicologia, de forma a que estes se tornem mais capazes de lidar com as adversidades da profissão.
ABSTRACT: In their work, psychologists dedicate themselves in helping their clients, so they can use their own resources in order to cope with their lives’ adversities; however, in order to take care of other people, professionals as well as students need to take care of themselves, so they can minimize the negative consequences of their practice in their performance. Self-care practices are associated with an increase of physical and emotional well-being e less perceived stress levels. The present study examined the association between sleep hygiene, physical activity, mindfulness and social support and perceived stress levels in psychology graduate students and young professionals presently attending internships. 113 interns (43 graduate students and 70 professionals) were evaluated through the International Physical Activity Questionnaire (2003), the Perceived Stress Scale (PSS-10) (2010), the Multidimensional Scale of Perceived Social Support (2011), the Philadelphia Mindfulness Scale (2008) and the Sleep Hygiene Index (2006), the latter two translated in the course of this study. Our results only showed a weak correlation between sleep hygiene (β=0,28, p<0,05), total social support (β=-0,33, p<0,05) and lower levels of perceived stress in professional interns. Further studies to broaden the knowledge in this field are necessary, so self-care practices can be implemented in training.

Texto completo da fonteAim: The overall aim of this thesis was to acquire knowledge about whether tactile touch as a complementary method can (i) promote comfort and (ii) reduce stress reactions during care in an intensive care unit (ICU) Method: In Paper I, five nurses with a touch therapist training were interviewed about their experiences of preparation before giving tactile touch in an ICU. To analyse the meaning of preparation as a phenomenon, Giorgi’s descriptive phenomenological approach was used. In Paper II and III a randomised controlled trial was set up to investigate the effects of a five-day tactile touch intervention on patients’ oxytocin levels in arterial blood (II), on patients’ blood pressure, heart rate and blood glucose level, and on patients’ levels of anxiety, sedation and alertness (III). Forty-four patients were randomised to either an intervention group (n = 21) or a control group (n = 23). Data were analysed with non-parametric statistics. In Paper IV, six patients who had received the tactile touch intervention were interviewed to illuminate the experience of receiving tactile touch during intensive care. To gain a deeper understanding of the phenomenon and to illuminate the meaning, Ricoeur’s phenomenological hermeneutical method, developed by Lindseth and Norberg, was used. Findings: The nurses need four constituents (inner balance, unconditional respect for the patients’ integrity, a relationship with the patient characterized by reciprocal trust and a supportive environment) to be prepared and go through the transition from nurse to touch therapist (I). In the intervention study, no significant differences were shown for oxytocin levels between intervention and control group over time or within each day (II). There were significantly lower levels of anxiety for patients in the intervention group. There were no significant differences between the intervention and control groups for blood pressure, heart rate, the use of drugs, levels of sedation or blood glucose levels (III). The significance of receiving tactile touch during intensive care was described as the creation of an imagined room along with the touch therapist. In this imagined room, the patients enjoyed tactile touch and gained hope for the future (IV). Conclusion: Nurses needed internal and external balance to be prepared for providing tactile touch. Patients did not notice the surroundings as much as the nurses did. Patients enjoyed the tactile touch and experienced comfort. The impact on stress parameters were limited, except for levels of anxiety which declined significantly. The results gave some evidence for the benefit of tactile touch given to patients in intensive care.

Texto completo da fontePreterm infants and their parents in the neonatal intensive care unit (NICU) are a growing client population for occupational therapists. The NICU environment of care can be over stimulating and cause high amounts of stress for preterm infants and their parents. Evidence-based literature supports preterm infant massage to decrease stress for preterm infants and improve overall neurobehavioral development. Evidenced-based literature also supports decreased stress for parents that perform preterm infant massage with their child as well as improved confidence of parental skills and infant-parent attachment. Despite these benefits, infant massage is practiced in less than half of the NICUs in the United States (Field, Diego & Hernandez-Reif, 2010). This may be related to the underlying mechanisms not being well understood and/or cost effectiveness considerations. This doctoral project (1) identifies evidenced-based literature to support the benefits of preterm infant massage for both the infant and the parent, (2) investigates evidence and best practice in designing a preterm infant massage parent education program in the NICU that supports the infant-parent dyad, (3) provides an overview of best practice for implementing a preterm infant massage parent education program in the NlCU, (4) describes a detailed evaluation plan and dissemination of the results including estimated budgets for implementation and dissemination. This project's target audiences are medical directors, directors of occupational therapy departments, neonatal occupational therapists, neonatologists, other health care staff in the NICU, and parents of preterm infants in the NICU. This project will be presented to the medical director of a Level IV NlCU and the director of occupational therapy at University of Rochester Medical Center-Golisano Children's Hospital for consideration of implementation. This project contributes to three areas of occupational therapy: (1) addressing best practice for implementing a preterm infant massage program in the NlCU to reduce stress levels for infants and parents, (2) providing more evidenced-based practice with a growing occupational therapy population of preterm infants and their parents, and (3) building a more diverse occupational therapy profession.

Texto completo da fonteIntroduction: Intrahospital transport of critical care patient is a responsible working operation and much of the critical care nurse and the assistant nurses´ work. It is risky, because incidents of patient and equipment can happen. Purpose: The objective was to describe the occurrence of incidents and types of incidents during intrahospital transport of ICU patients, and compare if there are differences in the occurrence of incidents during different times of day and the difference between emergency and planed transportation. The aim was to investigate nurses and assistans nurses´ perceived level of stress and fatigue during transport and if there are differences in the incidence of fatigue and/or stress during transport where incidents occurs or not occurs. Method: The study is quantitative, descriptive and comparative. The presence of the incident and the experience of stress/fatigue were answered on a response form of nurses and assistant nurse during or immediately after intrahospital transport. A total of 42 transports are included. Results: Adverse events occurred at 19 transports. No differences in the occurrence of incidents between day transports and night transport or between acute and planned transports could be seen. Nurses and assistant nurses reported more stress during the transports, where there have been adverse events than in those were adverse events had not occurred. Conclusion: Adverse events occurs in almost half of intrahospital transport and nurses and assistant nurses reported more stress associated with transports with adverse events other than the transports without adverse events.

Texto completo da fonteWork related stress is described as emotional state or mood, emerging from contradiction between work requirements and personal ability to fullfil them; this is personal perception of inability to perform the work tasks that are expected from him. Moderate strain at work acts as motivator and supply with energy to accept the challenges, although very high expectations and strong pressure results stress that negatively affects personell and organisation. There is the data about relationship of stress, its factors and symptoms with nurses age, family status and shift. The purpose – to investigate nurses‘ work related stress, satisfaction with work and intent to leave, and the relationship between these variables. Methods. Anonymous questionnairing was performed on 1-31 of May, 2012. Nurses of general practice and community care from four primary care centers of Kaunas city participated in the survey (N=280, response rate was 87,5%). All the respondents were females. The Extended Nursing Stress Scale with 56 items was used. Commettee on Bioethics at Lithuanian University of Health Sciences provided permission to perform this survey. Results: The most often stressful situation for nurses are related to patient‘s death and dying, also to situations of patient care and communication with his relatives. Discrimination was the rearest stresfull factor for nurses. Nurses are enthusiastic at work and the negative item that nurses dislike their work was scored with the lowest value... [to full text]

Texto completo da fonteThis experimental work is interested in understanding the flow downstream a short static swirler. Inducing a swirl motion is a known solution to increase the wall velocity gradient. The increase in wall shear stress is useful in industrial heat exchangers in order to enhance their heat transfer capabilities and reduce their fouling rates. We try to go deeper into knowledge of decaying swirl flows, for low Reynolds number for which energy interest is greater a priori. First, we study the flow field with optical methods in order to identify type of vortex characteristics of the swirl. Second, electrochemical method is used to measure the unsteady wall shear stress. By analogy, these measurements give a first estimate of the heat transfer for the case of non-isothermal flows
